4. Installation Instructions
The directions of EN 837-2 regarding selection and assembly of
the pressure gauge are to be observed.
Only qualified persons are authorized to handle the installation and
operation. Please observe the respective directions as well as the
advice of the manufacturer of fittings when screwing down the
process connections. The central PVDF-nut of the pressure gauge
which is sealed with a colour point as well as the screwing of the
pressure transmitter with the diaphragm seal may not be loosened
at any rate. This would cause the destruction of the measuring unit
and the leakage of the process media.
